Clean Air Metals Reports New Drill Results from both the Current Lake and Escape Lake Deposits of the Thunder Bay North Project including 76.7m of 5.67g/t PdEq with 21.0m of 9.98g/t PdEq

THUNDER BAY, ON, Sept. 7, 2021 /PRNewswire/ - Clean Air Metals Inc. ("Clean Air Metals" or the "Company") (TSXV: AIR) (FRA: CKU) (OTCQB: CLRMF) is pleased to announce new assay results from the drilling campaign currently underway at the Company's Thunder Bay North Project (the "Project"). Assay highlights (from Table 1) include:

For the Escape Lake deposit:

  • Hole ELR21-077 intersected 76.6m grading 5.67g/t Palladium Equivalents (PdEq)1 composed of 1.63g/t Platinum (Pt), 2.14g/t Palladium (Pd), 0.81% Copper (Cu), 0.41% Nickel (Ni) from 345.0m-421.6m downhole including 21.0m grading 9.98g/t PdEq composed of 2.97 g/t Platinum (Pt), 3.93g/t Palladium (Pd), 1.41% Copper (Cu), 0.68% Nickel (Ni) from 392.0m-413.0m downhole (Figure 1).

The Escape Lake Deposit has been the focus of the majority of the drilling over the past 14 months. Since the maiden resource published in January 2021 of 505,369 ounces at 3.67 g/t PdEq in 4.28 million tonnes, the Clean Air Metals team has successfully expanded the size of the Escape South High Grade Zone and demonstrated approximately 700m of mineralization along trend. Hole ELR21-077 with its significant thickness and grade appears to further expand the edge of the Escape Lake High Grade Zone and demonstrates potential contribution of scale of the Escape Lake Deposit to the overall Thunder Bay North Project. An updated mineral resource for the Escape Lake Deposit is currently planned for Q1 2022.

The Current Lake Deposit has a well-defined Indicated mineral resource of 1,328,789 PdEq ounces at a grade of 3.44 g/t PdEq in 11.99 million tonnes and is currently well advanced with a Preliminary Economic Assessment (PEA) study to be published in Q4 this year. The PEA-level mine stope optimization in the Beaver Lake Zone area of the Current Lake Deposit may be enhanced by the results of a recent infill drill program, including the following highlight results:

  • Hole CL21-007 which intersected 13.49m grading 6.09 g/t PdEq composed of 2.79 g/t Platinum (Pt), 2.61g/t Palladium (Pd), 0.52% Copper (Cu) and 0.31% Nickel (Ni) from 140.2 – 153.7m downhole (Figure 2).
  • Hole CL21-006 which intersected 14.83m grading 4.65 g/t PdEq composed of 1.92 g/t Platinum (Pt), 1.90g/t Palladium (Pd), 0.46% Copper (Cu) and 0.28% Nickel (Ni) from 152.2 – 167.0m downhole (Figure 2).
  • Hole CL21-008 which intersected 20.0m grading 3.43 g/t PdEq composed of 1.55 g/t Platinum (Pt), 1.41g/t Palladium (Pd), 0.26% Copper (Cu) and 0.20% Nickel (Ni) from 142.0 – 162.0m downhole (Figure 2).

Update on Metallurgy and PEA

Metallurgical optimization studies continue with Blue Coast Research of British Columbia. The results of the metallurgical studies on drill-derived bulk sample material and independent analysis of smelter recoveries and smelter payables are expected to input directly into a Preliminary Economic Assessment (PEA) mine cash flow model planned for publication in early Q4/2021.

Abraham Drost, CEO of Clean Air Metals stated that "infill assay results from the Beaver Lake Zone of the Current Lake deposit infill drilling ("CL" holes) is an affirmation of our understanding of the deposit and ability to target and execute on drilling which has the potential to materially impact the results of the upcoming PEA. This bodes well for future upgrade drilling on the large inferred resource down plunge which will occur at future study phases. The Company is looking forward to publication of a PEA in Q4/21 based solely on the Current Lake Deposit. As with the mineral resource estimate published in March, 2021, the PEA will be based on a ramp-access underground mine model constraining the existing mineral resource. In addition to the Current Lake Deposit, the potential to add scale to the Thunder Bay North Project with feed from the Escape Lake Deposit is potentially accretive to the project.

Recent drought conditions and regional forest fire activity imposed certain restrictions and precluded the construction of new drill pads on the Thunder Bay North Project. The Clean Air Metals geology team found innovative ways of keeping the drills running, including utilizing previous pads using angled holes to test edges and in the case of Hole ELR21-077, to expand the margins of the Escape South High Grade Zone. Fortunately, the drought has ended and the fire ban has now lifted. The present round of assay results is also being added to the Escape Lake deposit database ("ELR" holes) which will result in a revised mineral resource estimate in Q1/22."

COVID Policy

Clean Air Metals has adopted COVID-19 avoidance and personal protection measures for its geological staff, drilling contractor and service suppliers. Personnel are required to maintain physical distance, use Personal Protective Equipment (PPE), self-monitor and self-isolate or elect to work from home. Management had previously eliminated plans for a camp setup to service a planned diamond drill campaign on the Escape Lake Project. The Company is aware of Thunder Bay Health Unit guidelines that provide for "mandatory" self-isolation for returning overseas travel. The guidelines also "strongly recommend" self- monitoring and self-isolation as needed after travel into the Northwest region from other areas of the province and interprovincially. Mineral Exploration and Development has been deemed an essential service in the Province of Ontario (http://www.netnewsledger.com/2020/03/23/ontario-covid-19-business-allowed-to-remain-open-list-march-23-2020/ ).

Qualified Person

Mr. Allan MacTavish, M.Sc., P.Geo. a Qualified Person under National Instrument 43-101 and VP, Project Manager for the Company, has reviewed and approved all technical information in this press release.

Quality Assurance/Quality Control

Clean Air Metals uses ALS Global ("ALS"), a well-established and recognized mineral assay and geochemical analytical services company. The Thunder Bay laboratory holds ISO-9000 accreditation; the Vancouver facility holds ISO-17025 registration.

All NQ-sized drill core is cut with a diamond-tipped saw blade with half of the core submitted to ALS for sample preparation and analysis.  Core samples from selected intervals are individually bagged and tagged, gathered up in larger sealed poly bags and shipped to the sample prep facility in Thunder Bay, ON under custody of Clean Air personnel at all times. Sample preparation is completed at the ALS sample preparation facility located in Thunder Bay, ON and analysis is completed at the primary ALS assay laboratory located in Vancouver, B.C. 

Clean Air follows a documented quality control procedure for its core assay sampling program consisting of the insertion of blind blanks, duplicates, and certified Palladium-Platinum and Copper-Nickel standards into the sample stream.  The insertion procedure results in a minimum of 11% to 12% control sample frequency depending on the length of the sampled interval.

Gold, platinum, and palladium are analyzed using fire assay (FA) with an inductively coupled plasma mass spectrometry (ICP-MS) finish.  Samples with grades above the optimal ICP-MS detection limits are analyzed using an optical emission spectroscopy method (ICP-OES).

Also, thirty-three (33) elements of each sample, including copper, nickel, silver, chromium, cobalt, and sulphur, are analyzed by a multi-element analytical method using the atomic emission spectroscopy (ICP-AES) technique following four-acid digestion of the sample. When samples have grades above the optimal detection limits for this analytical method, they are re-analyzed using a high-grade method consisting of either ICP-AES or atomic absorption spectrometry (AAS) techniques.

Social Engagement

Clean Air Metals Inc. and its wholly-owned subsidiary Panoramic PGMs (Canada) Ltd. acknowledge that the Thunder Bay North Project is on the traditional territories of the Fort William First Nation, Red Rock First Nation and Biinjitiwabik Zaaging Anishinabek. The parties together are the Cooperating Participants in a Memorandum of Agreement dated January 9, 2021.

The Company is also in discussions with Red Sky Metis Independent Nation and the Metis Nation of Ontario and other non-proximate First Nation communities. Woodland Heritage Northwest, a Metis-owned consultancy has been retained to conduct archaeological studies on the Thunder Bay North Project and surrounding areas.
